Pinned topic Unable to install Biginsights

‏2013-10-10T14:58:13Z |

Hello every one.

I am trying to install Biginsights basic edition on an linux VM. The installation fails with the following message:

"[ERROR] Prerequisite check - Cannot use given credenital to access [oc7202628103.ibm.com], please revisit Secure Shell page from installer UI to make sure all prerequisites are satisfied, then re-run the installer."

This message has been received by other users but I have checked the log it is not the same. I have checked hosts, sudoers, sshd_config and, as far I am able to see, all point all right.

Any idea?

Thanks in advance.
